Journal: Journal of Clinical Oncology (2022)

e20013 Background: Autologous stem cell transplantation (ASCT) has improved long-term survival for many patients with multiple myeloma (MM), but not all patients respond to ASCT favorably, and many experience disease relapse. Our goal was to explore various disease parameters in patients with MM that might be associated with adverse outcomes after receiving ASCT. Methods: We performed a retrospective medical record review of adult patients with MM who underwent ASCT at Henry Ford Hospital between January 1, 2010 and November 1, 2020. Age, sex, international staging system stage, type of induction therapy, bone marrow cytogenetics and/or fluorescence in situ hybridization, International Myeloma Working Group (IMWG) treatment response criteria categories before ASCT, and the use of maintenance therapy were collected. Outcomes analyzed were time to relapse (TTR) and overall survival (OS). Cox regression analysis was performed. Results: A total of 321 patient records were analyzed: 194 (60.4%) patients were &lt; 65 years old; 185 (57.6%) were men; 162 (50.5%) were Black, and 140 (43.6%) were White. IMWG treatment response categories before ASCT included 250 (78.2%) patients with partial response (PR) and very good partial response (VGPR) combined, and 40 (12.5%) with complete response (CR). There were 69 (21.4 %) patients classified with high-risk cytogenetics. Commonly used induction therapies included 96 (29.9%) patients receiving bortezomib/lenalidomide/dexamethasone, 21 patients (9%) receiving lenalidomide/dexamethasone, 80 patients (24.9%) receiving bortezomib/dexamethasone, and 30 patients (9.3%) receiving cyclophosphamide/bortezomib/dexamethasone, while other patients received a combination of other induction therapies. Mean time from ASCT and last follow-up date was 3.94 years. The overall mean TTR was 29.4 months and OS was 44.8 months. Univariate analysis showed that pre-ASCT treatment response status of combined PR/VGPR was associated with higher hazard of dying than CR (hazard ratio 3.03; 95% CI, 1.23-7.46); however, multivariate analysis showed that PR/VGPR status before ASCT was not significantly associated with increased TTR compared to CR (hazard ratio 1.29; CI, 0.65-2.59). Patients with pre ASCT CR status had longer OS than those with PR/VGPR status (hazard ratio 2.75; CI, 0.995-7.61; p &lt; 0.05). No other variables, including cytogenetic risk were associated with a difference in OS or TTR. Conclusions: Being at CR status before receiving ASCT may indicate a reduced risk of death in MM patients compared to PR and VGPR status, regardless of upfront therapies. Since multiple factors, including treatment type, impact CR status in patients with MM, we believe that studying evolving risk-adapted front-line therapies will help guide optimized treatment strategies to improve overall survival.
Centralized care for the management of Barrett’s esophagus: the path forward or just an academic dream?
Authors: Arvind J. Trindade
Journal: Endoscopy (2022)

The incidence of esophageal adenocarcinoma (EAC) has been rising dramatically. Unfortunately the large majority of cases are diagnosed at late stages presenting with signs of dysphagia. Clearly, there are missed opportunities to screen and diagnose high risk patients earlier via endoscopic assessment. However, even among those who have undergone surveillance endoscopy for Barrett’s esophagus (BE), up to 24 % will still go on to develop EAC within 1 year [1]. This raises two questions: What are we doing wrong? How effective is endoscopic surveillance of Barrett’s esophagus at preventing esophageal cancer? In order to be effective, the endoscopist needs to perform a high quality examination and recognize high risk lesions. A high quality examination usually consists of documenting the pertinent landmarks [2] (e. g. location of the z-line and pinch, and the Prague criteria), spending 1 minute per centimeter of BE closely examining the mucosa using high definition endoscopy and electronic chromoendoscopy (e. g. narrow-band imaging), targeting visible lesions, and adhering to systemic biopsy protocols. Is this comprehensive examination better performed among centers of excellence for BE?

Journal: Journal of Clinical Oncology (2022)

e16276 Background: Endoscopic ultrasound-guided RFA (EUS-RFA) is a minimally invasive emerging modality that may be an alternative to surgical resection for the management of unresectable pancreatic cancer (UPC). In this review, we highlighted the efficacy, clinical and technical success of the EUS-RFA for UPC. Methods: Studies were selected with a comprehensive search strategy for EUS-RFA and pancreatic cancer on PubMed, Google Scholar, and Embase databases as of October 2021. The primary outcomes were the technical (TS) and clinical success rate (CS) of the EUS-RFA procedure, while the secondary outcome was the adverse events (AEs) rate. Results: Twelve studies including 114 patients with 50% (57) females were included. Common pancreatic tumors were locally advanced pancreatic ductal adenocarcinoma (LAPDAC) 38.3% (49), followed by nonfunctional neuroendocrine tumor (NNET) 32% (41), pancreatic cystic neoplastic lesions 14.8% (19), insulinoma 12.5% (16) and others 2.3% (3). The most common site of the tumor was pancreatic head 45.7% (59) followed by body, neck, and tail 47.6% (61). The average number of ablation sessions per patient was 1.4 based on the total of 115 EUS-RFA sessions performed in 84 neoplastic lesions. The pooled TS rate of EUS-RFA calculated from the total number of procedures was 99.2% [95% CI = 0.90-0.98, I 2 = 0%]. The pooled CS rate calculated from the total number of pancreatic lesions was 91.9% [95% CI = 0.77-0.92, I 2 = 0%]. Clinical improvement in symptoms was reported in five studies whereas complete resolution or decrease in tumor size was reported in all studies. The pooled AEs rate was 24.6% [95% CI = 0.17-0.39, I 2 = 30%]. Common AEs were abdominal pain 10.5% (12), and pancreatitis 3.5% (4). Conclusions: EUS-RFA is a promising and safe modality that can be used for the management of UPC in selected patients with a high TS (99.2%) and CS rates (91.9%). Large clinical trials are needed to identify safety, clinical outcomes, and overall survival benefits of EUS-RFA.[Table: see text]

Journal: Journal of Clinical Oncology (2022)

2567 Background: Liposomes deliver the drug to tumors based on enhanced permeability and retention (EPR) effects. Radiotherapy further prompts the distribution of liposomal drugs to tumor sites receiving radiotherapy by altering the tumor microenvironment. In addition, radiotherapy might enhance systemic antitumoral responses to immunotherapy. Herein, we aimed to explore safety and efficacy of radiotherapy in combination with irinotecan liposome, immunotherapy, and antiangiogenic therapy in advanced solid tumors patients (pts) that failed standard treatments. Methods: Anopen single-arm, multi-center, phase II study was conducted to enroll solid tumors pts who have failed standard treatments. Eligible pts would receive radiotherapy combined with irinotecan liposome followed by camrelizumab and apatinib. Radiotherapy of 24 Gy/3 fractions/3-10 days was given to the targeted lesions. Irinotecan liposome (80mg/m 2 i.v.) was administered once within 48 hours after radiotherapy and followed by camrelizumab (200mg i.v. q3w) and apatinib (250mg po qd) until disease progression or unacceptable toxicity. The primary endpoint was the objective response rate (ORR) of the irradiated lesions evaluated by the investigators as per RECIST V1.1. The secondary endpoints were disease control rate (DCR) and treatment-related adverse event (TRAE). Results: As of Dec 2021, 55 pts were enrolled includin 9 with biliary tract cancer, 8 with pancreatic cancer, 8 with sarcoma, 5 with lung cancer, 2 with liver cancer, 2 with cervical cancer, 2 with gastric cancer, and 22 with other cancer types. 26 (47.3%) pts failed at least 3 lines of therapy before enrollment. The median follow-up was 41 weeks and 42 pts can be evaluated. 15 partial response, 26 stable disease, and 1 progressive disease were achieved. The ORR and DCR of irradiated target lesions were 35.7% and 97.6%, respectively. The ORR and DCR of every cancer type are listed in table. TRAEs (all grades) occurred in 87.3% (48/55) pts. The most common grade 3-4 related TRAEs were lymphocyte count decreased (29.1%), white blood cell count decreased (10.9%), and anaemia (10.9%). Conclusions: The combination of radiotherapy, irinotecan liposome, camrelizumab, and apatinib demonstrated promising anti-tumor activity and well tolerance in various advanced solid tumors that failed standard treatments.

Abstract Atypical teratoid rhabdoid tumors (ATRT) are divided in three molecular subgroups, the so-called MYC, TYR and SHH subgroups. This heterogeneity suggests some diversity in the cells of origin, which remain hypothetical thus far. A careful radiological review of 55 MRI at diagnosis was performed in parallel with a careful analysis of mouse tumor origin in the Rosa26-CreERT2::Smarcbflox/flox model. Methylation, bulk RNAseq and scRNAseq analyses were integrated to these anatomic information to highlight potential origin for each molecularly and anatomically defined subgroups. We demonstrated that mouse Myc-ATRTs derive from extra-parenchymal meningeal areas, a finding consistant with many human MYC ATRT being clearly of intra-cranial extra-axial origin. Although this finding could point to a neural crest origin, transcriptomic features fail to unravel any lineage-specific signature. We also defined a distinct supra-tentorial SHH ATRT subgroup, characterized both in mouse and Humans by neural features pointing to the ganglionic eminence progenitors as the candidate origin. Finally we identified a distinct infra-tentorial SHH ATRT subgroup, not observed in mice, with hindbrain/midbrain boundary progenitor signature. scRNAseq from human SHH infra-tentorial tumors consistently suggest a dedifferentiation process involving the Notch pathway in the oncogenic transformation of hindbrain/midbrain neural progenitors.

8048 Background: Coronavirus-2 has profound effects on patients (pts) with Multiple myeloma (MM). At the beginning of the pandemic, COVID-19 infection resulted an overall mortality around 54% (cook et al. BMJ 2020). Here, we report an updated morbidity and fatality for MM. Methods: After obtaining IRB approvals from each participating institute, retrospectively, between January 1, 2021 and August 30, 2021, we identified pts with MM and COVID-19 in two myeloma centers (Levine Cancer Institute (LCI) &amp; the University of Kansas medical center (KUMC). Results: We identified 162 MM pts who had COVID-19 (LCI n=132, UKMC n=30), including 57% males, with median age of 64 years. Current or former smoking reported in 40% of pts. Most pts have associated comorbid conditions: hypertension (45%), hypogammaglobulinemia (32%), CKD (30%), DM (22%), obesity (16.6%), CHF (14%), and CAD (13.5%). Within 3 months prior to infection, treatment included immunomodulatory combinations in 35%, proteasome inhibitors in 28 %, and Daratumumab in 26.5%. Symptoms are summarized in table. 69% had Mild symptoms (no need for hospitalization), 20 % had moderate symptoms (requiring hospitalization), and 9.8% had severe symptoms (ICU level of care). The 18% of pts required oxygen: 6 pts required invasive oxygenation and 3 pts needed vasopressors. The 32% of pts had RRMM, 29.5% on maintenance, and 12% was getting induction. Regarding MM response: &gt;VGPR in 45% and PD in 18%. The 78 pts had ASCT prior to COVID-19 infection: only 3 pts &lt; 1 year and 3 pts &lt; 6 months. MM response or ASCT did not affect hospitalization or mortality.The case fatality rate (CFR) was 6%. In the univariate analysis, CKD, DM, HTN and hepatic dysfunction were associated with an increased risk of hospitalization. However, in multivariate analysis, only CKD, hepatic dysfunction, and Hypogammaglobulinemia significantly increased the risk of admission with only age and lymphopenia were associated with increased COVID-19 related fatatlity. Conclusions: With implementation of center-specific disease control measures and universal screening, pts might have lower case severity and fatality rate than was initially reported.

Journal: Neuro-Oncology (2022)

Abstract BACKGROUND: Therapy of infants with brain tumors predisposes these patients to increased risks for cognitive sequelae, especially following radiotherapy. Neuropsychological outcome gains importance for those 40-60% of patients with an atypical teratoid/rhabdoid tumor (ATRT) who survive beyond 2 years. Still, reports on cognitive late-effects in children with ATRT are scarce compared to other pediatric brain tumor groups. We analyzed neuropsychological outcome for long-term ATRT-survivors registered in EU-RHAB and infant low-grade glioma (LGG) survivors from the SIOP-LGG 2004-study and LGG-registry. PATIENTS+METHODS: Age at diagnosis of both cohorts was 0-36 months. ATRT-patients (n=13) treated with up to 54Gy radiotherapy (median age 22 months (±7.1)) were evaluated with the “ATRT-Neuropsychology” tool based on SIOPE-BTG QoS-Group recommendations at median 6.8 years (±2.8) after diagnosis. LGG-patients (n=15) treated without radiotherapy (4/15 with chemotherapy) were analyzed with the German “Neuropsychological-Basic-Diagnostic” tool 5.2 years (±0.6) post-diagnosis. RESULTS: The ATRT- vs. LGG-cohorts were comparable for median age at diagnosis, sex-ratio and tumor-localization, though they differed slightly in median age at assessment (9.5/7.2 years (±2.5/1.1)). Results of age-appropriate tests showed increased impairments for ATRT-patients in fluid intelligence (FI) (p=.006, d=1.214) and in visual-spatial processing (VSP) (p&amp;lt;.001, d=2.233) compared to LGG-patients. The median for neuropsychological test results of ATRT-patients spanned from considerably below the normal to the lower normal range (median=65-90), while results of LGG-patients were mostly in the lower normal range (median=83-103). Results for psychomotor speed abilities (PMS) were distinctly below the norm for both patient groups (p=.002-.007). CONCLUSION: Infant ATRT- and LGG-patients develop significant impairments in PMS abilities following multimodal treatment. Long-term survivors of ATRT suffer from additional FI and VSP deficits. Our data suggest that high malignancy requiring multimodal treatment determines the inferior cognitive outcome for the ATRT-cohort. Long-term neuropsychological monitoring (and treatment options) should be implemented as standard of care in ATRT- and LGG-trials.

Journal: Journal of Clinical Oncology (2022)

e12531 Background: 21-gene breast cancer recurrence-score assay (Oncotype DX) have been used to predict recurrence risks and guide adjuvant chemotherapy. However, access to such tests is limited, especially in a population concentrated with uninsured and underserved patient populations. Previously equations such as the Magee equation has been proposed to predict correlation of the recurrence score and the estimated recurrence score with high concordance rate. This study examines the concordance of such an assay to predicted scores in uninsured and underrepresented minority heavy public hospital. Methods: We performed a retrospective chart review of 68 women with hormone receptor-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer seen at University Hospital (public safety net hospital in Newark, New Jersey with greater majority of the patient population consists of underrepresented minorities such as Black/African Americans and Latino/Hispanics). 6 patients did not have pathology records, 9 patients did not have the Oncotype information available, and 4 patients were waiting on the results. Of the pre-menopausal eligible patients, two did not have any treatment or follow up information available and were included as part of the correlation assay, however, no. Results: Of the 47 eligible patients with follow-up information, 13 had a low recurrence score of up to 10 if post-menopausal and up to 15 if pre-menopausal, 22 had an intermediate recurrence score of 11 to 25 if post-menopausal and 16 to 25 if pre-menopausal, and 12 had a high recurrence score of greater than 26 according to the national comprehensive cancer network guidelines. The Pearson correlation between the Magee predicted score and Oncotype recurrence score was 0.73 (p &lt; 0.001). All patients received hormone therapy and 5 patients total had recurred. 2 were pre-menopausal and had received adjuvant chemotherapy. 3 were post-menopausal in low and intermediate categories who had not received adjuvant chemotherapy. Conclusions: This study shows a high correlation between the predicted Magee score and Oncotype recurrence score. This reflects a possible use in the prediction scoring system as another resource for prognostication and guidance in treatment especially in the underinsured population.

Abstract INTRODUCTION: Paediatric high-grade gliomas (HGG) are characterised by the aggressive biological behaviour with dismal prognosis of long-term survival 10-15%. Current molecular-biological diagnostic approaches allow for more precise characterization and determination of new unique subgroups of HGG. Our aim was to identify novel and rare HGG subgroups within our institution cohort. PATIENTS AND METHODS: Our reference centre patients′ cohort consisted of 97 clinically annotated patients with HGG diagnosed between 2000 and 2021. Sanger sequencing was used for screening of the most common HGG-related oncogenic drivers; furthermore we employed whole genome methylation array (Illumina Infinium MethylationEPIC BeadChip) and for selected samples RNA sequencing and expression profiling. RESULTS: Based on H3 status and previous radiotherapy we separated our HGG cases into the RIG, H3mut and H3wt groups. In contrast to H3mut(n=35) and RIG(n=11) that were uniformly fatal, H3wt group contained a proportion of long-term survivors. In the H3wt group we found patients carrying driver mutations in IDH1/2 (n=2) and BRAFV600E (7). Five young patients (under 3) consisted of 3 infant hemispheric gliomas (with NTRK and ROS1 fusions), one gliomatosis cerebri and one brainstem anaplastic astrocytoma with MYB/QKI fusion. We also identified a rare EWSR1-PATZ1 gene fusion in one patient. Importantly, long-term survivors recruited from these subgroups. On the contrary, four cases of MYCN GBM with poor prognosis presented in various locations: one disseminated, one gliomatosis cerebri and two with hemispheric tumour. We identified one patient with “hypermutated” glioblastoma and used targeted therapy with Nivolumab. In three samples of our patients with thalamic glioblastomas, we detected “loss of H3K27-trimethylation” caused by EZHIP overexpression. These tumours proved to be very aggressive with early metastatic recurrence and dismal prognosis. SUMMARY: Detailed characterization of H3 wild-type HGG is very important for further understanding of their biological behaviour, diagnostics, prognostication and identification of therapeutic targets.
